| Abstract | A major factor to the success of flexible manufacturing systems is their ability to transport work pieces between different workstations. Flexible manufacturing systems have now become more advanced and material handling systems have become progressively more sophisticated, it is not exceptional to have automated steering of tools to workstations as well. Such system design will improve the tool handling capability and will improve system productivity while holding tool cost to a minimum. Tool cost could represent as much as 25% of the operating cost. This research proposes a new Colored Petri Net based approach to the design and development of a tool sharing control system that is intended to help use of the proper and minimal number of tools for a manufacturing system. A new black token timed PN model is first developed, to reduce the complexity of the graphical representation we develop also a new colored PN model. The new colored PN model also allows finding the optimal sequence. The optimal sequence has no effect on the work in process but it influences the number of tools used in the system. |
